Brew Views: Your Sister’s Sister

Girls and boys and girls.

Your Sister’s Sister regards a bereaved
bloke (Mark Duplass) ferried to the Puget Sound cabin of his longtime
best friend (Emily Blunt), where he immediately and drunkenly tumbles
into bed with her lesbian big sister (Rosemarie DeWitt). The movie, by
Seattle director Lynn Shelton (Humpday), takes this
contrivance—the mumblecore equivalent of high concept—and works out the
results as naturalistically as possible, even making the heroes’
penchant for uniquely bad ideas into an ongoing subtext. If Your Sister’s Sister
feels good in the moment but doesn’t hold up under scrutiny, that’s
probably because DeWitt’s character, Hannah, is so indelible (and
intelligently performed) that she throws the love triangle out of
balance. By comparison, the other two thwarted lovebirds seem like a
stock rom-com couple in slow motion. But DeWitt’s in enough scenes, so
you don’t notice.
